The relation I believe will be still good between Pakistan and Malaysia but the different IMO is that Malaysia foreign policy will not intervene too much on Kashmir issue just like during Mahathir period. It is not because Muslim nation doesnt support Pakistan, but most Muslim nations dont like to complicate conflict between two Nuclear armed nations. The war between the two will create huge disaster. Keeping Pakistan in a safe state is in the interest of all Muslim, and the war between Pakistan and India will be cheered by both Israel and US tea party movement.There is nothing special just good relations for the time being. As soon as Erdogan is gone all good relations will go down the drain just as it happened with Malaysia after Mahatir left the office. Erdogan is the last leader of his kind after him there is no leader who has the will for similar relations with Pakistan. Economic relations will always triumph muslims brotherhoods in current world order. Relations with countries depend on present government and their policy direction not bcz we love each other. Pakistanis need to understand time of Ertgrul, Salah ud din ayubi is gone and no one will come to help us if we ever go to war with India or even those pidi ka shorba afghanis for a matter of fact.
The situation will change dramatically if dramatic event appear like India decide to invade Pakistani administered Kashmir. Similar way just like how Muslim nation blockade Israeli because Palestinian issue despite the blockade is against USA interest.
Current situation in Kashmir doesnt give much pressure to Muslim nation to change their relation with India dramatically.
